So I started a tub several months ago with 15 females and 15 males. It produces, but slowly. For the past several months I have had a lot of work done in my apartment so I keep my tubs in my closet on week days so the workers don't get the shock of tubs of bugs in my apartment after seeing 9 tanks of animals. I try to stay pretty under the radar with my apartment complex. Anyway on weekends I get the tubs out and plug them in with a heating pad. My colony gets roach chow and water crystals whenever they need it and fresh vegetables and greens weekly sometimes twice a week. I also add sugar to my colony, it was a tip from a pet store I hang out at, they seem to love it! So with those conditions what are good ways to increase my production? Also, a petstore I go to has dubia for sale. Thinking they would tell me no, I asked if they would sell me any of their adults. They were glad to so I grabbed 10 male and 10 female (after having to show the employee the difference). So my question about this is do you think this would be a good way to add females to my colony? They sell them for around $0.25 a roach which is awesome compared to what I see on ebay. Would it be a safe bet that I'm buying roaches that aren't all old and at the end of their breeding span?
